## Includes

    #include <libedataserver/libedataserver.h>

## Description

This modules provides utility functions for parsing and formatting phone numbers. Under the hood it uses Google's libphonenumber.

## Functions

### E_PHONE_NUMBER_ERROR

    #define E_PHONE_NUMBER_ERROR (e_phone_number_error_quark ())

### e_phone_number_error_quark ()

    GQuark
    e_phone_number_error_quark (void);

### e_phone_number_is_supported ()

    gboolean
    e_phone_number_is_supported (void);

Checks if phone number support is available. It is recommended to call this function before using any of the phone-utils functions to ensure that the required functionality is available, and to pick alternative mechanisms if needed.

#### Returns

`TRUE` if phone number support is available.

Since: 3.8

### e_phone_number_get_country_code_for_region ()

    gint
    e_phone_number_get_country_code_for_region
                                   (const gchar *region_code,
                                    GError **error);

Retrieves the preferred country calling code for `region_code` , e.g. 358 for "fi" or 1 for "en_US`UTF` -8".

If `NULL` is passed for `region_code` the default region as returned by `e_phone_number_get_default_region()` is used.

#### Parameters

region_code | a two-letter country code, a locale name, or `NULL`. | [allow-none]
error | a GError to set an error, if any. | [out]

#### Returns

a valid country calling code, or zero if an unknown region code was passed.

Since: 3.8

### e_phone_number_get_default_region ()

    gchar *
    e_phone_number_get_default_region (GError **error);

Retrieves the current two-letter country code that's used by default for parsing phone numbers in `e_phone_number_from_string()`. It can be useful to store this number before parsing a bigger number of phone numbers.

The result of this functions depends on the current setup of the `LC_ADDRESS` category: If that category provides a reasonable value for `_NL_ADDRESS_COUNTRY_AB2` this value is returned. Otherwise the locale name configured for `LC_ADDRESS` is parsed.

#### Parameters

error | a GError to set an error, if any. | [out]

#### Returns

a newly allocated string containing the current locale's two-letter code for phone number parsing.

### e_phone_number_from_string ()

    EPhoneNumber *
    e_phone_number_from_string (const gchar *phone_number,
                                const gchar *region_code,
                                GError **error);

Parses the string passed in `phone_number` . Note that no validation is performed whether the recognized phone number is valid for a particular region.

The two-letter country code passed in `region_code` only is used if the `phone_number` is not written in international format. The application's default region as returned by `e_phone_number_get_default_region()` is used if `region_code` is `NULL`.

If the number is guaranteed to start with a '+' followed by the country calling code, then "ZZ" can be passed for `region_code` .

#### Parameters

phone_number | the phone number to parse |
region_code | a two-letter country code, or `NULL`. | [allow-none]
error | a GError to set an error, if any. | [out]

#### Returns

a new EPhoneNumber instance on success, or `NULL` on error. Call `e_phone_number_free()` to release this instance.

### e_phone_number_to_string ()

    gchar *
    e_phone_number_to_string (const EPhoneNumber *phone_number,
                              EPhoneNumberFormat format);

Describes the `phone_number` according to the rules applying to `format` .

#### Parameters

                                     EPhoneNumberCountrySource *source);

Queries the `phone_number` 's country calling code and optionally stores the country calling code's origin in `source` . For instance when parsing "+1-617-5423789" this function would return one and assing E_PHONE_NUMBER_COUNTRY_FROM_FQTN to `source` .

#### Parameters

    gchar *
    e_phone_number_get_national_number (const EPhoneNumber *phone_number);

Queries the national portion of `phone_number` without any call-out prefixes. For instance when parsing "+1-617-5423789" this function would return the string "6175423789".

#### Parameters

phone_number | the phone number to query |

## Types and Values

### enum EPhoneNumberFormat

The supported formatting rules for phone numbers.

#### Members

E_PHONE_NUMBER_FORMAT_INTERNATIONAL | a formatted phone number always starting with the country calling code: "+49 30 55667788". |

E_PHONE_NUMBER_FORMAT_RFC3966 | a tel: URL according to RFC 3966: "tel:+49-30-55667788". |

Since: 3.8

### enum EPhoneNumberMatch

The strength of a phone number match.

Example 3. Some examples of phone number matches

Let's consider the phone number "+1-221-5423789", then comparing with "+1.221.542.3789" we have get E_PHONE_NUMBER_MATCH_EXACT because country code, region code and local number are matching. Comparing with "2215423789" will result in E_PHONE_NUMBER_MATCH_NATIONAL because the country calling code is missing, but the national portion is matching. Finally comparing with "5423789" gives E_PHONE_NUMBER_MATCH_SHORT. For more detail have a look at the following table:

| +1-617-5423789 | +1-221-5423789 | 221-5423789 | 5423789
--- | --- | --- | --- | ---
+1-617-5423789 | exact | none | none | short
+1-221-5423789 | none | exact | national | short
221-5423789 | none | national | national | short
5423789 | short | short | short | short

#### Members

E_PHONE_NUMBER_MATCH_NONE | The phone numbers did not match. |
E_PHONE_NUMBER_MATCH_EXACT | The phone numbers matched exactly. Two phone number strings are an exact match if the country code, national phone number, presence of a leading zero for Italian numbers and any extension present are the same. |
E_PHONE_NUMBER_MATCH_NATIONAL | The national phone number matched. Two phone number strings match at this strength if either or both has no region specified, and the national phone number and extensions are the same. |
E_PHONE_NUMBER_MATCH_SHORT | The weakest sort of match. Two phone numbers match at this strength if either or both has no region specified, or the region specified is the same, and one national phone number could be a shorter version of the other number. This includes the case where one has an extension specified, and the other does not. |

Since: 3.8

### enum EPhoneNumberError
